CUT-OFF TABLE FOR BRICK-MACHINES.

SPECIFICATION forming part of Letters Patent No. 515,383, dated February27, 1894.

Application filed November '7, 1893. Serial No. 490,245. (No model.)

To @ZZ whom it may concern:

Beit known that we, WILLIAM W.WALLAOE and RAYMOND C. PENFIELD, ofWilloughby, in the county of Lake and State of Ohio,have inventedcertain new and useful Improvements in Out-Off Tables forBrick-Machines; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use the same.

Ourinvention relates to an improved cut-off table for brick machines,wherein is provided, aat, smooth-faced horizontally-reci procatin gframe bearing a table for receiving thereon the bar or column of clay,and,in cutting the bar of clay into bricks, said table is movedlaterally or rearwardly from under the bar of clay and, by the sameoperation, an off-bearing board or pallet follows the table and takesits position under the bar of clay, so that, when the latter is severedinto bricks, thebricks rest on the pallet, the face of the tablemeantime being exposed and in position for cleaning and lubricating thesame. With the reverse movement of the parts, the pallet, laden with thebricks, retires to where it is out of the way of the next supply of clayto the table, and, during such next supply, the laden pallet is supposedto be removed from the machine and an empty pallet substituted therefor.The severing-wire-frame is carried forward and back by thereciprocating-frame and, hence, the severing-wires cut laterally throughthe bar of clay; but the severing-wires are mounted on alaterally-oscillating frame that is pivotally connected with theaforesaid reciprocating-frame, the oscillating-frame having preferably aroller that engages a stationary plate or surface by which engagementthe wire-bearing-frame, as it is moved to bring the wires intoengagement with the bar of clay, is, at the same time, tilted rearwardlyand downwardly, such compound movement imparting to the wires more orless end movement, relative to the bar of clay, resulting in what isknown as a draw-cut, and, at the same time, the downward movement of thewires upon the bar of clay makes a clean smooth cut along the upperedges of the bricks.

In the accompanying drawings, Figure lis a front side elevation, andFig. 2 is an end elevation of a cut-off -t-able embodying our invention,portions being broken away and in section to more clearly show theconstruction. Fig. 3 is an elevation of the severing-wireframe, and Fig.4 is a top plan, partly in section, of a portion of the severing-wireframe detached.

A represents a suitable supporting-frame bearing grooved rollers, a,that are arranged in pairs, usually at or near the respective ends ofthe structure. Upon said rollers is suitably mounted thetable-bearing-frame B, that, at each end, has a slotted bar orpiece, b,the internal parallel edges, b', whereof fit in the grooves of theaforesaid rollers. B designates the table of frame B. The upper surfaceof the table is flat and smooth so as to receive, with as littlefriction as possible, the bar or column of clay. By the front side oftable B is placed a removable pallet E (shown only in Fig. 2) that issupported by members h of the table-bearing-frame, and the latter hasfianges, lugs or suitable projections or attachments, b2, to hold thepallet snug against the table. The table and pallet are supposed to vbeiiush with each other on top, or, if otherwise, the top surface of thepallet should be somewhat lower than the top surface of the table.

The severing-wire-frame consists of two longitudinal bars or members Grlocated a suit-l able interval apart at the forward side of the frameand connected with each other, at opp The severing-wire-frame is locatedsomewhatreary wardly of the lower longitudinal bar ory mom'-v ber G ofsaid frame so that the severing-,wires incline rearwardly toward theirupper end. The severing-wires are arranged parallel with each other andseparated the one wire from the next adjacent wires the necessarydistance to sever the bar or column of clay into bricks of the desiredsize. The wire-bearingframe, preferably a suitable distance forward ofthe attachment of the lower ends of the severing-wires, is pivotallyconnected with IOO the horizontally-reciprocating table-bearing frame,B, the lower longitudinal bar Gr of the wire bearing frame beingpreferably provided, at each end,'with a forwardly-projecting flange orarm g. Members g at their outer side andforward extremity areprovided,respectively, with a trunnion g2 suitably j ournaled in the adjacentmember b of the horizontally-reciprocating frame B.

'The lower longitudinal bar G of the. wire.- bearing-frame, preferablyat its central portion, isprovided with a roller-bearing-bracket, I,that depends a suitable distance belowthe bar and has its roller Iengaging the back or inner side of a plate or member, K, rigid orintegral with the supporting-frame.

B-y the construction thus far described, it will be observed that whenthe table-bearingframeis reciprocated rearwardly to bring theo-bearing-board or pallet in under the bar 1 of clay being operatedupon, the oscillating wire-bearingf rame, bein gpivotall yconnected withthe reciprocating table, will move. rearwardly with thetablebearing-framaand thereby move thel aforesaid roller-bearing bracketfarther from the surface engaged by the roller ofsaid bracket, resultinginA the upward movement of said. roller on the bearing-plate` orsurface, andthereby permitting the. wire-'bearing-frame to tilt orosci-l.- late rearwardly anddownwardly by gravity. Upon the forwardreciprocation or return movement of the reciprocatingtablefbearingfframe, "the roller-bearing bracket of the wire# bearingifrarne'willagain approach. the plate or surfaee upon which the roller of saidbracket bears, resulting in the downwardl movement of the rolleruponsaid plate or surface into'its'normal position.

The lreciprocation of the table-bearing,E

frame isY effected by meansA ofahand-lever L that is operativelyconnected'with a shaft Z arranged lengthwise of andsuitably' supportedby frame Shaft Z, at or near each. end of frame A, is provided with arock-arm Z. Said rock-armsare set in line with each other. andareoperatively connected, by means of links Z2, with the adjacent member. bof the .table-bearing-frame.

The supporting-frame, at the rear side, is provided with a verticalstationary back,A,

that is located in a plane just above the top surface of table B and issupported at oppositeV ends by brackets a. rigid with thesupporting-frame. The table, is, therefore, adapted tov move' iu underback A during the rearward movement of the table-.bearing-frame and saidback, during such Inove-v ment of the frame, is adapted to push thebricks of clay from the table on to the offbeari'ng' board or pallet.With the return movement ofthe parts to the place of begin ning thebricks are carried by the pallet forf wardly out of the way, and thetable isvagain brought into position for receiving another dischargefrom the brick-machine.

By the construction hereinbefore described,

it will be observed that a compound-movement is given to thewire-bearing-frama the latter not only cutting the clay laterally but atthe same time cutting it downwardly,`

thereby effecting a clean cut along the upper surface of the clay.

Back A of the supporting-.frame has narrow slots a2 to receive theseveringwires as Athe latter approach the end of the cut, and,

, withstanding slots c2, has sufficient. Srength for the purpose forwhich, itis intended.
